The self-deploying structures seen in the world of nature, such as in shells, insect wings, and sunflower seed arrays, offer interesting topics of study for researchers in the fields of aerospace and mechanical engineering.
By doping the scales with carbon nanotubes they show that the amount of radiation that the wings can absorb increases, therefore improving the device's sensitivity.
However, if the wing aspect ratio is increased to more extreme values(i.e. the wings became even more elongated), then all flight performance characteristics decrease relative to the wild flies.
Dirk Zeuss and colleagues analysed wing and body colours of European butterfly and dragonfly species, and showed that dark and light colourations are indeed associated with cool and warm climates, respectively.
This suggests that the wing shape of wild flies is not optimised for all flight capabilities, but probably reflects the best trade-off among competing traits.
They found that when infrared radiation hit the wing, the air-filled photonic nanostructures heat up and expand, which causes the wing colour to change.
Expression analysis of wing-related genes revealed the two structures share key properties of wing development, suggesting a dual origin of the insect wing.
A total of 14 artworks with the shiny green wings of the scarab beetle reflect the light shining into the glass cube of Espace Louis Vuitton Tokyo and transform it into a space that displays not only the superficial beauty of the artworks but also a deep darkness hidden behind them.
For example, the authors note that C. anka and P. quercyensis display modifications to their antennae, wings and petiole(the narrow'waist' that separates the abdomen from the thorax), which make them better equipped for a ground-dwelling lifestyle compared to the two Xenomorphia species.
